This multi-surface car phone holder is designed for installation on a dashboard, windshield, or air vent, giving you flexibility based on your vehicle’s interior and your viewing preferences. The suction cup is made from heat-resistant TPU material, which is intended to remain functional in both hot and cold environments without melting or losing grip. To install, you press the suction cup button on a smooth surface to lock it in place; if the suction cup becomes dirty, it can be cleaned with warm water and air-dried to help restore its stickiness. The mount features a 360-degree adjustable base, allowing you to change the viewing angle without removing the suction cup, and an adjustable telescopic arm that extends from approximately 3.7 inches to 5.9 inches. The 360-degree ball joint supports both landscape and portrait viewing. An upgraded metal vent clip is also included, and the adjustable-length hook is designed to grip vent blades securely with a four-point mechanical support, compatible with both horizontal and vertical vents. The large adjustable foot is suitable for smartphones sized 4.0 to 7.1 inches and devices up to about 14 mm thick, and the extra-thick silicone layer on the clamp arm provides grip and scratch protection. This mount is suitable for sedans, pickup trucks, SUVs, taxis, and rideshare vehicles.
